Carbon dioxide: Part 11

Forget global warming: Welcome to the new Ice Age

While carbon dioxide has been pilloried as the cause of global warming which has caused the melting of the ice mass in the Arctic, that can hardly be the case as we saw in Carbon dioxide: Part 10.

Now two climatologists have concluded the wind has driven the ocean currents northward which in turn have melted the ice pack. The wind currents have a forty year cycle. Thus when the wind changes, the ocean currents change and the Arctic ice increases or decreases.

"We missed what was right in front of our eyes," says Prof. Russell. It's not ice melt but rather wind circulation that drives ocean currents northward from the tropics. Climate models until now have not properly accounted for the wind's effects on ocean circulation, so researchers have compensated by over-emphasizing the role of manmade warming on polar ice melt.

But when Profs. Toggweiler and Russell rejigged their model to include the 40-year cycle of winds away from the equator (then back towards it again), the role of ocean currents bringing warm southern waters to the north was obvious in the current Arctic warming.

So the experts did not know it all. They discovered something they did not know. Carbon dioxide is not increasing the earth’s temperature to melt Arctic ice. Rather the wind, in its long forty year cycle, has warmed the Arctic.

It’s nice to know some scientists can follow the evidence to the truth, rather than steer the evidence to the desired conclusion. Let’s see what The-earth-has-a-fever-Gore will say about this.
